DETAILED DESCRIPTIONThe following detailed description is merely illustrative in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any express or implied theory presented in the preceding technical field, background, brief summary or the following detailed description. For the purposes of conciseness, many conventional techniques and principles related to conventional staging, need not, and are not, described in detail herein.
One approach for staging is through an initial connection to a network component such as a staging server, relay server, etc. For example, a conventional approach for staging is using short message service (SMS) messages. In SMS staging, a services platform converts a selected staging profile into a sequence of encrypted SMS messages to the electronic device using one or more carriers. The SMS messages may be delivered to devices via email to SMS gateways provided by the carriers and/or via short message peer-to-peer protocol (SMPP) gateways contracted for with the carriers. Further conventional approaches includes bar code scanning, Ethernet based staging, and on-demand staging.
Techniques and technologies may be described herein in terms of functional and/or logical block components and various processing steps. It should be appreciated that such block components may be realized by any number of hardware, software, and/or firmware components configured to perform the specified functions. For example, an embodiment of a system or a component may employ various integrated circuit components, e.g., memory elements, digital signal processing elements, logic elements, look-up tables, or the like, which may carry out a variety of functions under the control of one or more microprocessors or other control devices.
The following description may refer to elements or nodes or features being “connected” or “coupled” together. As used herein, unless expressly stated otherwise, “connected” means that one element/node/feature is directly joined to (or directly communicates with) another element/node/feature, and not necessarily mechanically. Likewise, unless expressly stated otherwise, “coupled” means that one element/node/feature is directly or indirectly joined to (or directly or indirectly communicates with) another element/node/feature, and not necessarily mechanically. The term “exemplary” is used in the sense of “example, instance, or illustration” rather than “model,” or “deserving imitation.”
Technologies and concepts discussed herein relate to systems and methods of staging devices for use on a network. The network may be any conventional type of network. For example, the network may be a local area network (LAN), a wireless LAN (WLAN), a virtual LAN (VLAN), a wide area network (WAN), a wireless WAN (WWAN), a virtual WAN (VWAN), a metropolitan area network (MAN), a storage area network (SAN), etc.
The exemplary embodiments describe the staging of a mobile device that precludes a need for the mobile device to connect to a network component. Specifically, a secure digital (SD) card and/or an external storage unit includes a staging profile that is retrieved by the mobile device for application thereof. The staging, the mobile device, the SD card, the external storage unit, the staging profile, intermediate components of the system, and a related method will be discussed in further detail below.
It should be noted that the mobile device being staged is only exemplary. The exemplary embodiments may be used for any electronic device that requires staging. For example, the electronic device may be a terminal with a connector to the intermediate components. Thus, the mobile device as described herein may refer to both mobile electronic devices and stationary electronic devices.
FIG. 1 illustrates afirst system100 for staging amobile device102 according to an exemplary embodiment. Thefirst system100 enables themobile device102 to be staged without requiring themobile device102 to connect to a network component such as a staging server. Furthermore, thefirst system100 enables themobile device102 to be staged using only internal components and functionalities. Thefirst system100 includes a terminal104 with aterminal interface106 and acradle108 with acradle interface110, a universal serial bus (USB)hub122, and a plurality ofcradle ports124,126,118, and120.
Themobile device102 may be a new un-configured mobile device with wireless connectivity capability. Thus, themobile device102 may not be properly configured to connect to any network such as an enterprise. In one embodiment, themobile device102 can be configured to connect to other networks but not configured to connect to a desired enterprise. Thus, to properly be configured, themobile device102 is required to be staged.
Themobile device102 can include aprocessor122 and amemory124 for storing software applications for execution on theprocessor122. Thememory124 can also store information relating to themobile device102 such as one or more staging profiles. Themobile device102 can also include atransceiver126. Thetransceiver126 is configured to connect themobile device102 to a network. Themobile device102 can include an operating system executing on theprocessor122. Themobile device102 can also include abattery128 for powering themobile device102 and adisplay130 for displaying information relating to themobile device102.
The terminal104 may be any electronic device that is configured to receive and store at least one staging profile. For example, the terminal104 can include aprocessor132 and amemory134 for storing software applications for execution on theprocessor132. Thememory134 can also store information relating to the terminal104 or themobile device102 such as one or more staging profiles. The terminal104 can also include atransceiver136. Thetransceiver136 is configured to connect the terminal104 to a network. The terminal104 can also include one ormore interfaces106, such as a universal serial bus (USB) port interface.
A remote server can be configured to host a mobility service platform (MSP) application. The MSP application generates staging profiles that can be stored in thememory134 of the terminal104. The terminal104 can also include adisplay138 for displaying a graphical user interface (GUI) or any information relating to a network, the terminal104, and/or themobile device102. The terminal104 can be coupled to the remote MSP server withtransceiver136. In one embodiment, the terminal104 can be coupled to the remote MSP server through thecradle108.
The terminal104 may provide enhancements to a console user interface (UI) for a staging process. For example, the MSP console UI application residing on the remote MSP server may include an option to select one or more staging profiles for a local storage mode. Thus, the staging profiles may be saved locally on thememory134 of the terminal104. Furthermore, the staging profiles stored locally may be in a format that is appropriate for the staging according to the exemplary embodiments as will be described in further detail below.
According to an exemplary embodiment, the MSP application may create an encoded file (e.g., a ZIP file) representing a staging profile and enable storage of the encoded file locally on theterminal104. In an embodiment in which the MSP application resides on a remote server, the terminal104 may connect to the MSP server to retrieve the encoded file.
Once the terminal104 stores the staging profiles, theterminal interface106 may be utilized to connect to thecradle108 via thecradle interface110. The connection may be, for example, a USB interface. However, it should be noted that any connection may be used to enable communication between the terminal104 and thecradle108. According to the exemplary embodiment, thecradle108 includes the plurality ofcradle ports114,116,118, and120. Thus, thecradle108 may include theUSB hub122 for data exchange between thecradle interface110 and the cradle ports130-145. However, it should be noted that if thecradle108 includes only a single cradle port, thecradle108 may not include the USB hub112.
When themobile device102 is disposed in one of the cradle ports such ascradle port116, data may be exchanged between the terminal104 and themobile device102 via the above described intermediate components. The exchange of data between the terminal104 and themobile device102 may be performed using any conventional means such as ActiveSync® from Microsoft Corporation. Thus, it may be assumed that the terminal104 and themobile device102 are both configured with a common exchange means. It should be noted that the connection of thecradle108 may be readily recognized by the terminal104 via thecradle interface110 and theterminal interface106. Therefore, the terminal104 may prepare the data exchange accordingly. It should also be noted that themobile device102 may include further conventional functionalities to receive the staging profile such as a USB mode driver and USB physical driver. These functionalities may enable the connection between themobile device102 and thecradle108.
According to the exemplary embodiment ofFIG. 1, the connection between the terminal104 and thecradle108 may launch a specified utility for performing the data exchange of the staging profile. For example, the functionalities may include an auto-run file that launches the staging utility. Upon launching, the staging utility may detect that one or more valid staging profiles in the form of binary large objects (BLOBs) are present on theterminal104. The staging utility may subsequently prompt a user of themobile device102 as to whether one or more of the staging profiles are to be used for staging themobile device102. When the user selects at least one of the staging profiles, the staging utility may retrieve the corresponding staging profile BLOB(s) from the terminal104 and pass a proper command to a rapid deployment client to process the retrieved staging profile BLOB(s).
It should be noted that the above exemplary embodiment enables a single mobile device to be staged at a time. As the utility requires inputs from the user regarding which staging profiles are to be applied, the single mobile device is staged while other mobile devices that may be disposed within the cradle ports are pending. Once the staged mobile device disconnects, for example, from ActiveSync® (e.g., suspended, removed from cradle port, etc.), the terminal104 may connect to another mobile device.
FIG. 2 illustrates asecond system200 for staging amobile device202 according to an exemplary embodiment. Thesecond system200 also enables themobile device202 to be staged without requiring themobile device202 to connect to a network component such as a staging server. Thesecond system200 also enables themobile device202 to be staged using only internal components and functionalities. Thesecond system200 includes a card reader/writer204 that is configured to receive aSD card206 and acradle208 with acradle interface210, a USB hub212, and a plurality ofcradle ports214,216,218, and220. It should again be noted that themobile device202 requires staging such as themobile device102 ofFIG. 1.
Thecradle208, thecradle interface210, the USB hub212, and thecradle ports214,216,218, and220 may be substantially similar to those described above with reference toFIG. 1. Thecard reader204 may be an external component that is configured to connect to thecradle208 via areader interface222. The connection may be substantially similar to those used to connect the terminal104 to thecradle108 ofFIG. 1. Thecard reader204 may include aport224 to receive theSD card206 therein. TheSD card206 may be any secure storage device. TheSD card206 may be moved between multiple devices. Thus, prior to theSD card206 being disposed in theport224 of thecard reader204, data may be stored including the above described functionalities for initiating the staging utility. TheSD card206 may further store the plurality of staging profiles that may be available.
According to the exemplary embodiment ofFIG. 2, the receiving of theSD card206 in thecard reader204 may launch the staging utility for performing the data exchange of the staging profile. TheSD card206 may further include the auto-run file that launches the staging utility. Upon launching, the staging utility may detect that one or more valid staging profile BLOBs are present on theSD card206. Subsequently, a substantially similar process may occur as inFIG. 1 where a user is presented with a list of available staging profiles and a selection of one of the staging profiles is made. The corresponding staging profile BLOBs may be retrieved from theSD card206 with a proper command passed to the staging utility for the rapid deployment client to process the retrieved staging profile BLOBs.
It should be noted that according to the exemplary embodiment ofFIG. 2, themobile device202 may support a USB host mode. The interface between themobile device202 and thecradle208 may pass through the USB signals required for host mode. Thecradle interface210 may also support USB host mode. Thus, thecradle208 may grant a single mobile device exclusive control of thecradle interface210 at any time. Themobile device202 may include a USB host mode driver via a USB physical driver to perform USB client discovery over thecradle interface210. The host mode driver may discover thecard reader204 and load the USB ATA card driver to support it. The USB ATA card driver may detect theSD card206 and mount a FAT file system to provide access to the contents of theSD card206. The staging utility may subsequently access theSD card206 via the file system. In a substantially similar manner asFIG. 1, when the stagedmobile device206 closes theSD card206, thecradle208 may grant exclusive control of thecradle interface210 to another mobile device.
FIG. 3 shows athird system300 for staging amobile device302 according to an exemplary embodiment. Thethird system300 also enables themobile device302 to be staged without requiring themobile device302 to connect to a network component such as a staging server. Thethird system300 also enables themobile device302 to be staged using only internal components and functionalities. Thethird system300 includes substantially similar components as thesecond system200 ofFIG. 2. Thethird system300 includes a card reader/writer304 having aport305 that is configured to receive aSD card306 and acradle308 with acradle interface310, anATA storage manager312 with a plurality of USB/ATA emulators314a,314b,314c,314d, and a plurality ofcradle ports316,318,320, and322. It should again be noted that themobile device302 requires staging such as themobile device202 ofFIG. 2.
Thecard reader304, thereader interface324, theSD card306, thecradle308, thecradle interface310, and the plurality ofcradle ports316,318,320, and322 may be substantially similar to those described above with reference to thesystem200 ofFIG. 2. In contrast to thesecond system200, thethird system300 may include theATA storage manager312. TheATA storage manager312 may act as a USB host and have exclusive control of thecradle interface310. TheATA storage manager312 may discover thecard reader304 and theSD card306 plugged into theport305. TheATA storage manager312 may mount a FAT file system to provide access to the contents of theSD card306.
Thecradle ports316,318,320, and322 may each be connected to the USB/ATA emulators314a-d, respectively. The USB/ATA emulators314a-dmay look to the mobile device in the correspond cradle port such as themobile device302 in thecradle port322 as if it were thecard reader304 with theSD card306 disposed therein. Themobile device302 may include a USB host mode driver that discovers the emulated USB ATA reader and load the USB ATA card driver to support it. The USB ATA card driver may detect theSD card306 and mount a fat file system to provide access to the contents of theSD card306. The staging utility may access theSD card306 via the file system. TheATA storage manager312 may coordinate requests received from multiple devices via the plurality of USB/ATA emulators314a-d. TheATA storage manager312 may perform access to theSD card306 to service the requests received from the plurality of USB/ATA emulators314a-d. TheATA storage manager312 may optionally cache data to improve performance by avoiding the need to access the same data from theSD card306 repetitively. Therefore, thethird system300 may function in a substantially similar manner as thesecond system200 but further enable multiple mobile devices to be staged concurrently.
FIG. 4 shows afourth system400 for staging amobile device402 according to an exemplary embodiment. Thefourth system400 also enables themobile device402 to be staged without requiring themobile device402 to connect to a network component such as a staging server. Thefourth system400 includes aEthernet cradle404 with acradle interface406, an Ethernet hub/switch408, a plurality of USB network interface controllers (NICs)410a,410b,410c,410d, and a plurality ofcradle ports412,414,416, and418. It should again be noted that themobile device402 requires staging such as themobile device302 ofFIG. 3.
Thecradle404 may be configured to support multiple concurrent access to an external network component such as a network attached storage (NAS)hard disk420. The NAShard disk420 may be connected to thecradle404 via thecradle interface406 which may be, for example, a 802.3 RJ45 Ethernet port. Themobile device402 may support USB host mode and the interface between themobile device402 and thecradle port418 may pass through the USB signals required for the host mode. Thecradle interface406 may also support the USB host mode. Themobile device402 may include a USB host mode driver via a USB physical driver that performs USB client discovery over thecradle interface406. The host mode driver may discover the USB NICs410a-dand load remote network driver interface specifications (RNDIS) driver to support it. The RNDIS driver may interact with the USB NICs410a-dto gain access to the Ethernet interface (e.g., cradle interface406) via the Ethernet hub/switch408.
Themobile device402 may acquire a TCP/IP stack to obtain an IP address from aDHCP server422. The staging utility may access a file or folder on the NAShard disk420 by using a UNC path to the desired file or folder. The device common internet file system (CIFS) redirector may coordinate access to the files and folders on the NAShard disk420 by using the CIFS protocol via the TCP/IP stack. Thus, thefourth system400 also enables multiple mobile devices to be staged concurrently.
FIGS. 5A and 5B illustratemethods500,501 used for staging a mobile device without requiring the mobile device to connect to a network component according to an exemplary embodiment. Specifically,FIG. 5A illustrates anexemplary method500 for generating and storing a staging profile.FIG. 5B illustrates anexemplary method501 for staging a mobile device. Themethods500,501 will be described with reference to thefirst system100 ofFIG. 1, thesecond system200 ofFIG. 2, thethird system300 ofFIG. 3, and thefourth system400 ofFIG. 4.
Referring toFIG. 5A, instep502, a preparatory step includes logging into a MSP server. Instep504, a staging profile may be generated by the MSP server. Instep506, the staging profile may be selected to be stored locally. As discussed above, the staging profile may be encoded and stored in a local device. For example, in thefirst system100, the encoded staging profile may be stored in the terminal104; in thesecond system200, the encoded staging profile may be stored in theSD card206; in thethird system300, the encoded staging profile may be stored in theSD card306; and in thefourth system400, the encoded staging profile may be stored in the NAShard disk420.
Referring toFIG. 5B, instep508, the staging utility may be initiated. As discussed above, the staging utility may be initiated automatically. For example, in thefirst system100, the connection established between the terminal104 and thecradle108 may execute an auto-run file that initiates the staging utility. In another example, in thesecond system200 and thethird system300, theSD card206/306 may include the auto-run file so that reception of theSD card206/306 in thecard reader204/304 may initiate the staging utility. In yet another example, in thefourth system400, the disposition of themobile device402 in thecradle port418 may indicate to thecradle404 that themobile device402 requires staging, thereby initiating the staging utility.
Instep510, the staging utility provides a list of the available staging profiles for the user of the mobile device to select. Instep512, the staging utility retrieves the staging profile BLOB from the storage unit to apply to the mobile device. As discussed above, the local storage option of the staging profile may generate the respective staging profile BLOB. Thus, when the staging profile is selected, the staging profile BLOB may be retrieved and decoded from the terminal104, theSD card206, theSD card306, and/or the NAShard disk420.
The exemplary embodiments allow a mobile device to be staged without ever requiring the mobile device to connect to a network component or requiring any other conventional modes of staging. According to a first exemplary embodiment, a plurality of staging profiles may be received at a terminal that connects to a cradle. A staging utility may determine selected staging profiles to be applied to the mobile device.
According to a second exemplary embodiment, a plurality of staging profiles may be stored in a SD card that is disposed in a card reader that connects to a cradle. Through a USB hub, the mobile device may be staged one at a time. According to a third exemplary embodiment, a plurality of staging profiles may be stored in a SD card that is disposed in a card reader that connects to a cradle. Through a ATA storage manager, multiple mobile devices may be staged concurrently. According to a fourth exemplary embodiment, a cradle may connect to network components and have the staging utility retrieve selected staging profiles from a NAS hard disk. In each exemplary embodiment, the mobile device is only required to be disposed in a cradle port of the cradle. The mobile device is not required to connect to a network component to facilitate staging.
Those skilled in the art will understand that the above described exemplary embodiments may be implemented in any number of manners, including, as a separate software module, as a combination of hardware and software, etc. For example, the staging utility may be a program containing lines of code that, when compiled, may be executed on a processor.
In general, the processor can include processing logic configured to carry out the functions, techniques, and processing tasks associated with the operation of the mobile device.

Any such software may be implemented as low level instructions (assembly code, machine code, etc.) or as higher-level interpreted or compiled software code (e.g., C, C++, Objective-C, Java, Python, etc.).
In the foregoing specification, specific embodiments have been described. However, one of ordinary skill in the art appreciates that various modifications and changes can be made without departing from the scope of the invention as set forth in the claims below. Accordingly, the specification and figures are to be regarded in an illustrative rather than a restrictive sense, and all such modifications are intended to be included within the scope of present teachings. The benefits, advantages, solutions to problems, and any element(s) that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as a critical, required, or essential features or elements of any or all the claims. The invention is defined solely by the appended claims including any amendments made during the pendency of this application and all equivalents of those claims as issued.
Moreover in this document, relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” “has”, “having,” “includes”, “including,” “contains”, “containing” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises, has, includes, contains a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises . . . a”, “has . . . a”, “includes . . . a”, “contains . . . a” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises, has, includes, contains the element. The terms “a” and “an” are defined as one or more unless explicitly stated otherwise herein. The terms “substantially”, “essentially”, “approximately”, “about” or any other version thereof, are defined as being close to as understood by one of ordinary skill in the art, and in one non-limiting embodiment the term is defined to be within 10%, in another embodiment within 5%, in another embodiment within 1% and in another embodiment within 0.5%. A device or structure that is “configured” in a certain way is configured in at least that way, but may also be configured in ways that are not listed.
It will be appreciated that some embodiments may be comprised of one or more generic or specialized processors (or “processing devices”) such as microprocessors, digital signal processors, customized processors and field programmable gate arrays (FPGAs) and unique stored program instructions (including both software and firmware) that control the one or more processors to implement, in conjunction with certain non-processor circuits, some, most, or all of the functions of the method and apparatus described herein. The non-processor circuits may include, but are not limited to, a radio receiver, a radio transmitter, signal drivers, clock circuits, power source circuits, and user input devices. As such, these functions may be interpreted as steps of a method to perform the mobile device staging described herein. Alternatively, some or all functions could be implemented by a state machine that has no stored program instructions, or in one or more application specific integrated circuits (ASICs), in which each function or some combinations of certain of the functions are implemented as custom logic. Of course, a combination of the two approaches could be used. Both the state machine and ASIC are considered herein as a “processing device” for purposes of the foregoing discussion and claim language.

It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the foregoing Detailed Description, it can be seen that various features are grouped together in various embodiments for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed embodiments require more features than are expressly recited in each claim.
